Distinguishing lensing and precessional modulation in binary black-hole inspiral waveforms
Tien N. Nguyen-Vo, Tamanjyot Singh, Benjamin McKallip +2
Binary black holes (BBHs) emit gravitational waves (GWs) as they inspiral towards merger. These GWs can be gravitationally lensed by large-scale structure along the line of sight,…

Detecting regular precession using a new gravitational waveform model directly parameterized by both precession amplitude and frequency
Tamanjyot Singh, Evangelos Stoikos, Saif Ali +3
Nearly 210 binary black hole (BBH) mergers have been observed by the LIGO-Virgo-KAGRA network during its four observing runs. Generic BBHs are spinning, and their spins are misalig…

Identifying multiple images of gravitational-wave sources lensed by elliptical lensing potentials
Saif Ali, Michael Kesden, Lindsay King
Real astrophysical lenses typically lack axisymmetry, necessitating the study of gravitational-wave (GW) lensing by elliptical mass distributions to accurately assess detectability…
